2.4 Attaching a Cable (RJ-45)
Solarflare 10GBASE-T Server Adapters connect to the Ethernet network using a copper cable fitted
with an RJ-45 connector (shown below).
RJ-45 Cable Specifications
Table 1 below lists the recommended cable specifications for various Ethernet port types.
Depending on the intended use, attach a suitable cable. For example, to achieve 10 Gb/s
performance, use a Category 6 cable. To achieve the desired performance, the adapter must be
connected to a compliant link partner, such as an IEEE 802.3an-compliant gigabit switch.
